I am not a Christian but I put up a christmas tree etc and do the Christmas thing for my kids. I don't really see how that's hypocritical, though, because Christmas was NOT CHRIST'S birthday, but a rip on a pagan holiday, Yule. The Christian Church decided sometime during the dark ages that it was easier to adopt and "Christianize" pagan holidays than it was to enforce their own. Even proper "Christians" would NOT celebrate Christmas because they felt it was a PAGAN holiday. So all the Christians that have their panties in a bunch over your "hypocrasy" should go home and look in the mirror, or perhaps just do a little research.
